Illustrative Hypotheticals Do Not Show Legal-Standard Error in USSG § 3B1.2 Denials When the Record Reflects Comparative Culpability Analysis

1. Introduction

In United States v. Valdez, the Tenth Circuit reviewed whether a district court applied the wrong legal standard when it denied a defendant a mitigating-role adjustment under USSG § 3B1.2. Jasmine Rae Valdez pled guilty to assault with a dangerous weapon in Indian country and assault resulting in serious bodily injury in Indian country under 18 U.S.C. §§ 113(a)(3) & (6), 1151, 1152, with the government proceeding on an accomplice theory, 18 U.S.C. § 2, because Valdez did not personally strike the victim (D.C.).

The key sentencing issue was whether Valdez—who fought with the victim’s girlfriend at the doorway/inside the home while two others attacked the victim in the bedroom—was “substantially less culpable” than the “average participant” in the criminal activity, such that she qualified for a mitigating-role reduction. On appeal, Valdez reframed the dispute as a legal-standard error (not merely a factual disagreement), but she had not raised that particular legal-standard objection below—triggering plain-error review.

2. Summary of the Opinion

The Tenth Circuit affirmed. Applying plain-error review, it held Valdez failed at the first prong because the district court did not apply an incorrect legal standard. The panel rejected Valdez’s argument that the district court’s hypotheticals (an unwitting driver and an innocent bystander) showed the court treated “non-culpability” as the threshold for USSG § 3B1.2 relief. In context, the district court conducted a comparative, totality-of-the-circumstances assessment—placing Valdez’s conduct on a “continuum of involvement,” considering her knowledge and participation, and concluding she was not sufficiently peripheral to warrant a reduction.

3.1 Precedents Cited

• Cortez v. Bondi, 150 F.4th 1320 (10th Cir. 2025)
  Cited only for the court’s practice of using initials for juveniles. It does not influence the substantive sentencing analysis, but it explains the opinion’s anonymization convention for “G.W.”
• United States v. Berryhill, 140 F.4th 1287 (10th Cir. 2025)
  Berryhill supplies the controlling framework for plain-error review when an argument is not preserved in the district court. The Valdez panel relies on Berryhill for the four-prong test and the proposition that unpreserved claims are reviewed only for plain error.
• United States v. Caraway, 534 F.3d 1290 (10th Cir. 2008)
  Caraway is cited for a key structural point of plain-error doctrine: failure on any prong defeats relief. This mattered because the panel resolved the appeal at prong one (no error), making prongs two through four irrelevant.
• United States v. Caruth, 930 F.2d 811 (10th Cir. 1991)
  Caruth is used to rebut a common misconception in mitigating-role litigation: being “less culpable” than codefendants does not automatically equate to “minimal participant” or entitlement to a mitigating-role reduction. In Valdez, this principle supports the district court’s view that “not striking the victim” is not dispositive and that relative culpability requires a broader role-based assessment.
• United States v. Yurek, 925 F.3d 423 (10th Cir. 2019)
  Yurek is the appellant’s primary comparator. The Valdez panel distinguishes it: Yurek involved a “complete failure” to measure culpability against other participants and an approach that treated a single factor as dispositive. By contrast, the Valdez district court repeatedly discussed Valdez’s role as “different” from the others and evaluated knowledge/participation under the guidelines’ multifactor approach.
• United States v. Wireman, 849 F.3d 956 (10th Cir. 2017)
  Wireman is cited for the appellate practice of stopping the analysis once plain error is not established at an earlier prong. It supports the panel’s decision not to address prongs two through four after finding no error.

3.2 Legal Reasoning

(a) The governing guideline rule. The opinion anchors its analysis in the text and commentary to USSG § 3B1.2. A mitigating-role reduction depends on the “totality of the circumstances” and considers (among other things) “the degree to which the defendant understood the scope and structure of the criminal activity” and “the nature and extent of the defendant’s participation.” The touchstone is whether the defendant is “substantially less culpable than the average participant in the criminal activity.”

(b) The appellate lens: plain error, not de novo. Because Valdez did not argue below that the court used an incorrect legal standard, the panel applied plain-error review (via United States v. Berryhill). This matters: on plain error, it is not enough that the defendant might plausibly have qualified for the reduction; the defendant must first show the district court actually erred in the legal standard or application.

(c) Contextual reading of the sentencing judge’s remarks. Valdez’s appellate theory focused on the district court’s hypotheticals—an unwitting driver and an innocent bystander—as purported proof the court required “non-culpability” to get the adjustment. The panel rejected that reading by situating the hypotheticals within the judge’s broader explanation:

• The judge described role reductions as typical for “peripheral” actors lacking knowledge of the larger scope—language consistent with the guideline commentary’s emphasis on knowledge and participation.
• The judge expressly treated Valdez as a culpable participant but “different” from Mr. Rains and G.W., reflecting the comparative posture required by the guideline.
• The judge used a “continuum of involvement,” placing the hypotheticals at one extreme to illustrate what “truly peripheral” might look like, not to impose a legal eligibility floor of innocence.
• The judge relied on concrete facts that map onto § 3B1.2 factors: Valdez knew an altercation was “envisioned,” entered the home, blocked the door, and engaged in her own fight while the assault on D.C. occurred.

(d) “Not striking the victim” is relevant but not dispositive. The district court acknowledged Valdez “was not directly involved” in imposing serious bodily injury, but the panel emphasized that role analysis does not end there, aligning with United States v. Caruth (less culpable does not automatically mean minimal participant).

(e) Distinguishing Yurek. The panel treated United States v. Yurek as the boundary case: reversal is warranted where the sentencing court fails to conduct the required comparative culpability assessment and improperly treats one factor as decisive. In Valdez, the district court’s comparative discussion and multifactor evaluation prevented that characterization.

(f) “Illustrative imprecision” is not legal error. Even if the hypotheticals sounded like actors who would lack culpability altogether, the panel held that imprecise illustrations do not establish legal error when the court’s operative analysis reflects the correct comparative standard. That holding is the opinion’s core clarifying point for future § 3B1.2 challenges framed as legal-standard claims.

3.3 Impact

(1) Appellate strategy and preservation: Valdez underscores the practical cost of not preserving a “wrong legal standard” objection at sentencing. On appeal, defendants may try to recast a discretionary role determination as legal error, but plain-error review creates a high barrier—especially where the record contains any reasonable indicia that the judge performed the correct comparative assessment.

(2) Sentencing-record construction: District judges in the Tenth Circuit can expect that appellate courts will read their remarks in context, focusing on whether the § 3B1.2 “average participant/totality” framework was applied. Colorful hypotheticals and imperfect analogies are unlikely, by themselves, to justify reversal if the judge otherwise engaged the proper factors.

(3) Clarifying the “continuum” method: The opinion implicitly approves a “continuum of involvement” narrative as a permissible way to organize mitigating-role analysis, provided it remains anchored to the guideline’s comparative culpability inquiry (knowledge, scope, participation).

(4) Substantive role-reduction signal in violent-assault accomplice cases: In assault prosecutions premised on accomplice liability, “I didn’t hit the victim” will rarely be sufficient, standing alone, to compel a mitigating-role adjustment; courts will scrutinize facilitative conduct (e.g., entry, obstruction, diversionary fighting) and foreknowledge of the confrontation.

4. Complex Concepts Simplified

• Mitigating-role adjustment (USSG § 3B1.2): A reduction in the guideline offense level for defendants who are “substantially less culpable” than the “average participant.” It is not automatically granted just because someone did less than a codefendant; the court weighs the whole context (knowledge, planning, actions, importance to the offense).
• “Average participant”: Not an abstract “typical criminal,” but a comparison point drawn from the participants in the criminal activity at issue. The question is whether the defendant’s role is substantially less culpable than that benchmark.
• Plain-error review: A deferential standard applied when an argument was not preserved in the trial court. The defendant must show an obvious error that affected substantial rights and undermined the proceedings’ fairness. If there is no error at step one, the appeal ends.
• Accomplice liability (18 U.S.C. § 2): A person can be guilty of an offense even if they did not personally commit every physical act, so long as they aided, abetted, or otherwise assisted the commission. That is why “not striking the victim” does not necessarily equate to a minor role.
• “Indian country” jurisdiction (18 U.S.C. §§ 1151, 1152): Federal jurisdictional statutes that bring certain crimes occurring in Indian country within federal prosecutorial authority, depending on the status of the parties and location. In this case, they establish the federal forum; the disputed issue was sentencing, not jurisdiction.
• Nonprecedential “Order and Judgment”: The decision is not binding precedent for future panels, but it can be cited for persuasive value and is binding in the same case under certain doctrines.

5. Conclusion

United States v. Valdez reinforces that a district court does not apply an incorrect legal standard under USSG § 3B1.2 merely by using hypotheticals that resemble non-culpable actors, so long as the court’s actual analysis reflects the guideline’s required comparative, totality-of-the-circumstances evaluation. The opinion also highlights the decisive role of preservation: when a defendant fails to raise a legal-standard objection at sentencing, plain-error review will often foreclose relief unless the record clearly demonstrates a genuine departure from the guideline’s comparative culpability framework.
